There is some focus on incorporating media queries and setting up the projects for a mobile view, but it has not been heavily teaching about that, at least not up to this point. Perhaps the second major project will have more focus on that? But you can take a look at the syllabus for it and decide, of course.

@Kingwindie
is there anyway to make the background of a navigation bar transparent without the li items inthe nav bar disappearing?
Ken Haduch
@khaduch
@Kingwindie - are you using rgba colors with some opacity? What does that look like?
Kingsley
@Kingwindie
@khaduch nevermind thanks,i found a solution

@xtine88
i don't understand the Factorilization of the Numbers algorithm
I semi got the answer...but it doesnt make sense to me...can someone explain it?
Ken Haduch
@khaduch
@xtine88 - could you post your code?
Christine de la Fuente
@xtine88
yes sir

@xtine88
I understand the for loop
however, I don't understand why I need to set var x = 1
Ken Haduch
@khaduch
@xtine88 - one thing that you are not doing is returning the final value - console.log doesn't return the value. then...
Christine de la Fuente
@xtine88
oh yes, I just put console log...to print it in the command line to test out
other wise I wouldn't see it
Ken Haduch
@khaduch

@xtine88 - the definition of 0! is that it is equal to 1. If the incoming value is 0 your loop will never run, so the value will remain at 1 and that is what you want to return. That's the main reason.

And to complete the function you have to actually do return x; after the loop, at the same place you have console.log(x);

Christine de la Fuente
@xtine88
what's the difference between return x and console.log(x)? isn't console.log(x) the same as a return x only that its printing it?
would you say that "var x = 1" is just a way to enter the loop?
Ken Haduch
@khaduch

@xtine88 - no, console.log(x) doesn't return a value from the function, it might return a value (probably a meaningless one) to the place where you called console.log, but for all intents and purposes, it doesn't return a value. Especially not from the function. You can leave it there for debug purposes, but you have to have an explicit return x; otherwise you get an implicit return undefined;

And you could look at var x = 1; as a way to enter the loop - initializing the value, but since it isn't really a loop-control value, maybe it's not technically correct to call it anything having to do with entering the loop. Basically I would just think of it as initialization of the variable. And if you do no further computation to modify the variable, that will be the final answer.

Hi, I'm on the tribute page for the basic front end and am having issues with properly centering my lists
Ken Haduch
@khaduch
@LucarLeo - is your page on CodePen - want to post your URL, if it is?
Lee
@LeeConnelly12
@LucarLeo try putting all of the list items in one ul
<ul style="list-style: none;">
            <li class="list-txt">What does she do?</li>
            <li class="list-txt">Sits on a guy's shoulder. </li>
            <li class="list-txt">does angry lala noises </li>
            <li class="list-txt">trusts you </li>
            <li class="list-txt">What she doesn't do:
            <li class="list-txt">tall people that isn't her personal portable chair </li>
            <li class="list-txt"> tall people who don't pet her before speaking</li>
            <li class="list-txt"> tall people who look down at her</li>
        </ul>
Ken Haduch
@khaduch
@LucarLeo I don't see lists on your page? Oh, wait, you changed the styling... Centering lists like that doesn't work if you want the list to be left-justified (like a normal list view.)
One way to do it is to set up a bootstrap grid row and pick a central set of columns to contain the data of your list. There might be other ways to do it, too -
Lee
@LeeConnelly12
@LucarLeo Also, you're missing an end div tag in your html just above your lists
<div class="nano-bg">
    <h1 class="brnz-text">Nanamo Ul Namo</h1>
    <h5 class="brnz-txt"> the ultimate cinnamon roll</h5>
    <img class="smaller-img img-center" src="http://chrysaliswiki.wdfiles.com/local--files/people:nanamo-ul-namo/nanamoulnamo_ff14.png"
        alt="a cute angry lalafell"></img>
    </>

@LucarLeo - on codepen, all of the CSS should be in the CSS panel, for correct usage of codepen.
Lance LeBlanc
@LucarLeo
I'm just getting back into coding in general, so all of this is still a bit newish
Ken Haduch
@khaduch

@LucarLeo - one thing that you can do, to center the lists without the center-justification, is to use flex. For example, wrap the two divs that you have your lists with another div, and on that parent div, add a class like class="flex-center" and in your CSS panel, define .flex-center like this:

.flex-center {
    display: flex;
    flex-direction: column;
    align-items: center;
}

See if that gives you the effect that you are looking for?

Ken Haduch
@khaduch
@LucarLeo - I neglected to mention that I commented out the text-align: center; from your .list-txt class declaration.
@LucarLeo - the screenshot of what it looks like with those settings (just the central portion of the screen)

Lance LeBlanc
@LucarLeo
I think the part I was trying to say (which the misunderstanding is on my part) is that I wanted to keep it as the format it was in, but trying to get it to move more center without having to take it out of <ul>

Ken Haduch
@khaduch
@LucarLeo - it might be better to take it out of the <ul> and just use <p> tags for each item? I'm going to try that - I see what you are having problems with, there is some built-in margin or padding in the list to separate the text from the bullet. Or just use a <div> to wrap each line - that eliminates the baggage of the <ul> and the <li>. The first four lines in this next screen shot are structured that way.

Hey guys, I need some help. I'm working on the simon says front end project and am trying to loop through an array that contains the sequence of colors. This loop adds a class that represents the color lighting up, then should remove the class so the color goes dim again. However, my colors never go dim. Can anyone tell me what's wrong?
for(var i = 0; i <= sequence.length; i++){
$("#" + sequence[i]).addClass('brightLight');
setTimeout(function(){
$("#" + sequence[i]).removeClass('brightLight');
}, 1000);
}
}
For reference, here's the codepen link. If you try hitting start, you'll see what I mean
Ken Haduch
@khaduch
@sunorei - the problem is that the for loop will run through without regard to the timeout values - and at the end of the timeout, the value for i will be 1 beyond the end of the array, so it will not access anything. One thing to try first is instead of using var i try using let i - that changes the behavior of the value within the loop. It still won't work properly as far as the sequence of events, but I think that it might make the class be removed at the end.
Amin
@hanamin
Hmm ok I'll have to consider it. On a side note, is there a benefit to use let over var? From what I understand the only difference is scope, correct?
The course didn't cover let at all iirc
Lee
@LeeConnelly12
@sunorei You can't re declare let variables
in the same scope anyway
